Tooth for tooth

Dissertationes Archaeologicae
Until the Hadrianic period, large bronzes had a naturalistic appearance due to polychrome elements. One element on the statues of gods, heroes and portraits that has been studied rarely are the inserted white teeth. They were invented in the late archaic or early classical period and disappeared on the large statues with the decline of the Hellenistic ...

Harnessing smart nanomaterials to reprogram neutrophil plasticity in immune modulation

Journal of Nanobiotechnology
Neutrophils are the most abundant type of white blood cells in the immune system and play a complex and intricate regulatory role in disease progression. Their critical contribution to maintaining homeostasis through migration, activation, and programmed

Matrix Stiffness Governs Fibroblasts’ Regulation of Gingival Immune Homeostasis

Advanced Materials, EarlyView.
This study identifies a “mechano‐epigenetic” checkpoint in which matrix stiffness governs the immune responses of gingival fibroblasts. Using biomimetic hydrogels and human gingival explants, the studies revealed that restoring extracellular matrix stiffness actively suppresses inflammation via non‐canonical NF‐κB signaling and DNA methylation ...

RETRACTED ARTICLE: Identification and assessment of differentially expressed necroptosis long non-coding RNAs associated with periodontitis in human

BMC Oral Health, 2023
Background Periodontitis is the most common oral disease and is closely related to immune infiltration in the periodontal microenvironment and its poor prognosis is related to the complex immune response.

Double tooth.

Collegium antropologicum, 2002
The form of primary and permanent teeth can differ morphologically from that which is considered normal, completely or in some parts. The changes in tooth form can be hereditary or caused by some disease or trauma. Fusion is a union of one or more teeth during development.

Downregulation of FGF Signaling by Spry4 Overexpression Leads to Shape Impairment, Enamel Irregularities, and Delayed Signaling Center Formation in the Mouse Molar. [PDF]

, 2019
FGF signaling plays a critical role in tooth development, and mutations in modulators of this pathway produce a number of striking phenotypes. However, many aspects of the role of the FGF pathway in regulating the morphological features and the mineral ...

Crack Repair in Hydroxyapatite Bioceramics Using an Ultraviolet Ultrafast Laser

Advanced Materials Interfaces, EarlyView.
The study proposes an ultrafast ultraviolet laser approach to repair hidden tooth cracks, which has been preliminarily validated on HAP. Moreover, this technique aims to strengthen the native enamel structure rather than introducing a foreign filling material.

General tooth boundary conditions for equation free modelling [PDF]

, 2006
We are developing a framework for multiscale computation which enables models at a ``microscopic'' level of description, for example Lattice Boltzmann, Monte Carlo or Molecular Dynamics simulators, to perform modelling tasks at ``macroscopic'' length ...

Toward Wireless Implantable Robotic Systems Driven by Magnetic Field for Personalized Therapy

Advanced Robotics Research, EarlyView.
Robotic materials are playing an increasingly vital role in enabling sensing and actuation at small scales. This perspective highlights recent advances in magnetic materials and magnetically actuated devices for wireless sensing, actuation, and energy harvesting toward implantable robotic systems for closed‐loop therapy.
